Modeling Surface Processes on Debris-Covered Glaciers: A Review with Reference to the High Mountain Asia
Published in Water, Huo, D., Chi, Z. & Ma, A., 2021
This review summarizes our current knowledge of surface processes on debris-covered glaciers with an emphasis on the related modeling efforts. We present an integrated view on how numerical modeling provide insights into glacier surface ablation, supraglacial debris transport, morphological variation, pond dynamics, and ice-cliff evolution. We also highlight the remote sensing approaches that facilitate modeling, and discuss the limitations of existing models regarding their capabilities to address coupled processes on debris-covered glaciers and suggest research directions.

Understanding Complex Debris-Covered Glaciers: Concepts, Issues and Research Directions
Published in Frontiers in Earth Science, Huo, D., Bishop, M. P. & Bush, A., 2021
This paper is about glacier modeling. Our results demonstrate that climate forcing, the properties and transport of debris, topography and supraglacial water bodies are the key controlling factors in a debris-covered glacier system, and that their coupled effects and positive feedbacks may increase the ice loss of a debris-covered glacier. We also recommend new research directions for future studies.
